It’s common to see desktop weather monitors that include a thermometer and
barometer and predict fine or stormy weather based on changes in air pressure.
This
Oregon
WMR100 Scientific weather station goes further. Although its base station
has the same type of screen display, there is a lot more on it, as it connects
wirelessly to two external sensors to monitor wind direction and strength as
well as temperature and rainfall.
These sensors took some assembly and careful mounting, with staples and guy
ropes in the case of the wind sensor. All the kit is well made with – for
example, a three-piece steel pole to mount the wind monitor on and a mesh gauze
to filter detritus out of captured water in the rain gauge.
The electronic set-up was made particularly easy by the automated nature of
the system. The wind and rain sensors connected automatically and were
calibrated with minimal intervention, though we did have to use a compass to
tell the wind sensor which way north was.
The base station picks up the time from the atomic-radio clock at Cumbria and
adjusts its calendar and moon phase display as soon as it gets an accurate time.
There is a mini-USB socket on the side of the base station which connects to
a PC and, once you have downloaded the display software from the
Oregon
Scientific website, it’s possible to feed weather data through to this
program for logging and display.
From a usability point of view the software is the weak link as it has a much
more complicated – and rather untidy – design and little of the automated setup
that was such a strong feature of the rest of the package.
The users have to determine arcane settings such as which Com port the base
station is connected to (not obvious with a USB connection) and the latitude and
longitude of your location, together with its height above sea level.
If you get around this lot, the software is pretty thorough. It can log
readings from the weather station so you can see how weather events progress
over time. It will not necessarily help with prediction, but the whole station
is more about monitoring and recording than guessing tomorrow’s weather.
